Abstract

The embodiment of the present application discloses a data transmission method, terminal equipment and network equipment. The method includes: the first terminal equipment determines the transmission mode of the packet data convergence layer protocol PDCP protocol data unit PDU, and the transmission mode includes a copy data transmission mode Or a single-link transmission mode; the first terminal device sends the PDCP PDU to the second terminal device or network device according to the transmission mode of the PDCP PDU. The method, terminal device, and network device in the embodiments of the present application help balance the relationship between resource utilization and reliability of data transmission.

Description

[0001] This application is a PCT international patent application PCT / CN2017 / 077931 with an application date of March 23, 2017, which entered the Chinese national phase. The Chinese patent application number 201780088784.X, the title of the invention is "method for transmitting data, terminal equipment and network equipment" divisional application. technical field [0002] The embodiments of the present application relate to the communication field, and more specifically, relate to a method for transmitting data, a terminal device, and a network device. Background technique [0003] In the carrier aggregation scenario, the packet data convergence layer protocol (Packet Data Convergence Protocol, PDCP) protocol layer sender can support the data replication function, that is, copy a PDCP protocol data unit (Protocol DataUnit, PDU) into two copies (possibly multiple copies), In this way, the reliability of data transmission is improved. In the prior art, the direct use of the ...
